Companies located outside the UK who have reproduced items, and tried to use a facsimile of the marks or numbering system have been sued, and have had sanctions imposed against them. This tends to protect the use of these marks, and in general restricts them to use on pieces made in the UK. This protects both collectors and the companies who registered the marks.

MASON’S PATENT NOV 30TH 1858 Fruit Jars – Summary

Hemmi was granted Japanese patent in for laminated bamboo construction and success seems to have followed quickly thereafter. One can estimate dates of Hemmi slide rules from markings on the rules. I have not been able to narrow the date. Rules with model numbers date from before this changeover, rules with model numbers 20 and above were made after the changeover.

Hemmi continued offering models 1, 5 and 8 to its distributors until WWII or later; these rules occasionally turn up with Post or Hughes-Owens model numbers but no Hemmi model number. The company name was officially changed from “J.

These are also recently-made imports from Asia. His improvement revolutionized home canning in the United States.

There is no absolute proof of that, however. Another firm which was producing the jars early on was the Consolidated Fruit Jar Company, perhaps making them as early as or Questions remain on exactly which companies made these jars during the early years, since the patent evidently lasted 13 years or 20 years, counting a patent reissue , and ostensibly during that time period no one was allowed to produce the jars because of patent infringement issues unless they were granted permission by Mason, or the licensed holder of the patent.

In any case, throughout the next odd years, production of jars with the Nov. The s and s likely saw the peak of popularity of these jars. A considerable percentage have a mold number or letter on the base, a means of identifying the particular mold in use at the factory. Contrary to a popular misconception, these jars were not made in wooden molds, but in metal molds, usually made of cast iron or steel. Some examples also have identifying initials on the base or reverse, or a monogram on the front or back, which can serve to identify what company made them.

History[ edit ] BT’s origins date back to the establishment of the first telecommunications companies in Britain.

John Hudson, with his other premises in nearby Shudehill. The first exchange was opened in London in August , closely followed by the Lancashire Telephonic Exchange in Manchester. In it became the primary supplier of telecommunications services, after the Post Office took over the private sector telephone service in GB, except for a few local authority services. Those services all folded within a few years, the sole exception being Kingston upon Hull , where the telephone department became present day KCOM Group.

In the Bridgeman Committee produced a report that was rejected. A committee was set up to look into the advantages and disadvantages of the proposal, and its findings were found to be favourable enough for the Government to re-establish a Steering Group on the Organisation of the Post Office. After some initial deliberations that the business should be divided into five divisions; Post , Telecommunications, Savings , Giro and National Data Processing Services, it was decided that there should be two: These events finally resulted in the introduction of the Post Office Act,

A patent is a type of intellectual property protection that gives inventors of new devices and designs the exclusive legal right to produce and use their inventions for a certain period of time. The duration of a patent depends on the type of patent and when the patent was issued. Patent and Trademark Office offers online patent information that can be used to figure out the expiration date of a patent. Go to the U.

To look for a patent of invention issued between and October , first find the reference number and year in the printed indexes, available at The National Archives, the British Library and in several reference libraries.

One rich source of information is found in the United State Patent Office which registers invention patents, design patents, trademark registrations, and label registrations. If your collectible has a patent number then information about its history is recorded. Most any large city library will have a complete set of these documents, the most useful to bottle collectors is the Patent Office Official Gazette.

All of the patents, designs, trademarks and labels were recorded in a document known as the Official Gazette. These were published weekly, and bound into hard bound volumes by the year. By the later part of the 19th century, it required anywhere from two to four volumes to list and describe all of the issuances for a given year.

The amount of bottle related information thaty can be found in the Official Gazette is astonishing. There are perhaps 10, items relating to insulators, fruit jars, medicines, mineral waters, beers, whiskeys, perfumes and hundreds of other items.

History[ edit ] Carbon tetrachloride CCl4 was used in fire extinguishers and glass “anti-fire grenades” from the late nineteenth century until around the end of World War II. Experimentation with chloroalkanes for fire suppression on military aircraft began at least as early as the s. Freon is a trade name for a group of CFCs which are used primarily as refrigerants , but also have uses in fire-fighting and as propellants in aerosol cans.

Bromomethane is widely used as a fumigant. Dichloromethane is a versatile industrial solvent. In the late s, Thomas Midgley, Jr. In searching for a new refrigerant, requirements for the compound were: In a demonstration for the American Chemical Society , Midgley flamboyantly demonstrated all these properties by inhaling a breath of the gas and using it to blow out a candle [6] in Nevertheless, after the war they slowly became more common in civil aviation as well.

In the s, fluoroalkanes and bromofluoroalkanes became available and were quickly recognized as being highly effective fire-fighting materials. Much early research with Halon was conducted under the auspices of the US Armed Forces, while Halon was, initially, mainly developed in the UK. By the late s they were standard in many applications where water and dry-powder extinguishers posed a threat of damage to the protected property, including computer rooms, telecommunications switches, laboratories, museums and art collections.

Beginning with warships , in the s, bromofluoroalkanes also progressively came to be associated with rapid knockdown of severe fires in confined spaces with minimal risk to personnel.

Those three date ranges are differentiated by the presence or absence of certain case and movement markings as well as the nature of any such markings, as explained below. In general, for all time periods, it is important to understand that Bulova watches never provide an obvious date of manufacture anywhere on the watch. Rather, the date must be “de-coded” using symbols, serial numbers, and two-character codes placed on various parts of the watch.

These codes and the manner in which they should be interpreted is the subject of this article. Many observers of Bulova watches are confused by the sometimes seen patent dates stamped on the inside of some Bulova watch cases, and they misinterpret such dates as the time of manufacture. In point of fact, those patent dates apply only to certain aspects of the case design and indicate only when those general designs were patented.

Dating early Monopoly games is done by the patent numbers and cities listed on the labels. Most early games can be dated within a few years using these label elements. Canadian Monopoly games were introduced in and closely resembled the U.S. games with the different varieties.

Guide Alfred Dunhill began to manufacture briar smoking pipes in ; the famous white spot first appeared on top of the hand-cut vulcanite mouthpiece in in order that the customer should know which part faced upwards. At about this same time a one year guarantee against defects was offered on the bowl of each pipe, and to insure against far older Dunhill pipes being replaced under this guarantee a simple dating code, showing the year of manufacture, was devised and stamped onto each pipe bowl.

This code is still in use today. Over the ensuing years great interest has arisen over the “mystique” of the Dunhill pipe in general and the dating code in particular. Pipe collectors, especially in America, pride themselves on having acquired Dunhill pipes in prime condition which were made in the ‘s, ‘s and ‘s.

Some collectors strive to acquire only those Dunhill pipes made between when Dunhill stopped buying bowls turned in France in favor of those turned in London at the newly opened Dunhill bowl-turning facility and the year of Alfred Dunhill’s retirement. Consequently, much confusion has arisen over the dating code because it has not been standardized over the years, and seemingly minor differences in the code can mean a difference of years, even decades, in the manufacture of the pipe. Adding to this is the fact that the firm has used a great many special stampings depending on what part of the world to which their pipes were destined, and that sometimes these stampings or codes were used for only three or four months duration.

Leading to even greater confusion is that many pipes were simply stamped incorrectly; at times one part or another of the code is not to be found on a given pipe. Taking all this into account it should not be surprising that the original and complete dating code list, in possession of the firm’s archivist at 30 Duke Street, is some twenty eight pages long.

And even if this list was made available it would be of little use to any but the most expert because it can only be used in conjunction with the most precise knowledge of the Dunhill pipe as it has changed in appearance over the years. But enough of the complications in dating Dunhill pipes.
